Paul is the author and the the speaker in Philippians 3 and he is saying that while he is saved he still sins and he has to press on towards the goal of following Christ which will end when he is called to Heaven and the good work that God began in him is completed.
Oh, so they found a copy of the Horus legend that mimics the Christ story from before the time of Christ? When did that happen? Or are you just repeating tired arguments that have no basis in actual fact and display an astonishing ignorance of not one but two faith systems?
It does, Christians need to be more familiar with Romans, particularly the fourteenth chapter where Paul warns about things like this happening and says that it is wrong.
